Table of Contents - Delete default "Introduction"?

Using Camtasia 9.0.1 to create a table of contents in Smartplayer. The first 'link' created is "introduction". All the items in the table of contents are created by placing "markers" on the timeline of the project. "introduction" is not on the timeline, and I can't find it anywhere else.

Yes you can do as Kayakman suggests - but either way, there is no option to uncheck including the first marker in a custom production because the checkbox is greyed out. If I delete the text using rename, then Camtasia adds "Untitled Marker" as the name in production.

I don't understand why our productions should be forced to have a marker at t=0

Interesting thought, but I just discovered a definitive way to get rid of the t=0 marker:

After production, go into the "scripts" subfolder that was created by production, then open config_xml.js with notepad and search for the code that instructs the player to add the first marker. It might look something like this:

Delete this full line, then it's not added at all to the table of contents.

The same text is also in the root production folder named [Yourprojectname]_config.xml I assume this should be removed too because I'm guessing this is used maybe as a backup if javascript isn't working or for some other reason.
